A non-slip draining board is provided to work securely without slip by forming a non-slip part in a flat part, to integrate the draining board with concrete by increasing the contact area, and to prevent deformation or crack of concrete by flexibly and easily arranging the draining board with convex and concave parts. A non-slip draining board(1) includes plural opening parts protruded downward from a flat part(10), a recessed part(20) formed between the opening parts, a reinforcing rib(25) connecting the opening part to the recessed part and increasing the connection rigidity, an assembling part formed at a side of the flat part, and a non-slip part(40) unevenly formed in the flat part to increase friction force. The flat part is flexible, and the assembling part includes plural assembling projections(33) protruded downward at two sides of the flat part, and plural assembling grooves(35) arranged in an extension part and formed corresponding to the assembling projections. |
